Please help me answer this question.
Suppose that y is directly proportional to x, and y = −16 when x = −2. What is the constant of proportionality?
A) −8
B) −
1
8
C) 1
8
D) 8
Answer:
In the given expression the constant of proportionality is k = 8.
Step-by-step explanation:
The quantity P is said to be directly proportional to Q if they vary in proportion to each other.
Here, P ∝ Q ⇔ P = kQ : k = Proportionality Constant
Now, here given y ∝ x and x = -2, y = -16
Now, y ∝ x ⇒ y = kxor, (-16) = k (-2) or, k = 16/2 = 8 ⇒ k = 8So, for k = 8, y ∝ x
Hence, in the given expression the constant of proportionality is k = 8.

Answer:
(36 + 14) ÷ 10 = 5
Step-by-step explanation:

Answer:
B. He should focus on females because the ratio of females to males is 5:2.
Step-by-step explanation:
By looking at the graph, you can see that there are 25 females and 10 males. The ratio for this is 25:10, but we can simplify by dividing both sides by 5! 25/5=5, and 10/5=2, so the simplified ratio of 25:10 is 5:2. If you look at all of the answer choices, you really don't have to look at the words a lot; there's only one choice that includes the ratio 5:2. That choice is B, so B is the answer!
Hope this helps you out!! Have an amazing day o(*^▽^*)o
